A multiple-module, oil-flooded, rotary screw compressor wherein a plurality of compressor modules are driven by a single drive shaft. The modules are positioned in parallel so that a large volume of compressed air can be provided for use in equipment which continuously requires a large supply of such air. The compressor is configured so that each rotary screw compressor module includes a driven gear engaged with the same gear on the drive shaft. The compressor modules may share a common inlet cavity and a common outlet cavity.

1. A multi-module rotary screw compressor comprising:a compressor casing having an inlet cavity for receiving a fluid to be compressed; a plurality of rotary screw compressor modules positioned such that each of said rotary screw compressor modules receives the fluid directly from said inlet cavity, each of said rotary screw compressor modules including a male rotor intermeshed with a female rotor; a drive shaft operatively connected to the compressor modules; a drive gear mounted to said drive shaft; wherein rotation of said drive shaft causes said male rotors to rotate; and wherein rotation of each of said male rotors causes said female rotors to rotate and thereby compress the fluid received from said inlet cavity.
